Why Trane | System components | Warranty | Maintenance       Climatuff Compressor       Spine Fin Coil       Powder Paint       Duratuff Basepan       back Powder Paint Protecting What is Inside One of most recognizable attributes of Trane outdoor product is its high gloss powder paint finish. Not only is this high gloss finish a consistent winner with consumers, but it is also a tried and true durability feature. The quality begins with the metal itself. Untreated (non-stabilized) galvanized steel is used so it will accept Trane’s optimum paint pretreatment. Pretreated steel can lose its zinc phosphate during forming and handling. By using untreated steel, we can apply the corrosion fighting zinc phosphate ourselves, ensuring that the entire part is coated after it is formed and handled.
